Abstract:

This report presents a comparison of the predictions of the PROPHET and HFBC84 field strength models to observed data. Both models are described and plots of various statistical quantities relating to their predictive performance are given. Both models show large average residual and root mean square residual in predictions for frequencies which exceed the maximum useable frequency for a mode. The HFBC84 model shows large error for path lengths greater than 7000 km. The author suggests replacement for the current PROPHET field strength model based on the results of the comparison.
